> I've been testing [Brotli|https://github.com/google/brotli/], a new
> compression library based on LZ77 from Google. Google's [brotli
> benchmarks|https://cran.r-project.org/web/packages/brotli/vignettes/brotli-2015-09-22.pdf]
> look really good and we're also seeing a significant improvement in
> compression size, compression speed, or both.

> {code}
> Brotli, at quality 1, is as fast as snappy and ends up smaller than gzip-9.
> Another test resulted in a slightly larger Brotli file than gzip produced,
> but Brotli was 4x faster. I'd like to get this compression codec into Hadoop.
